Instruction Manual
5. How to Wiring for the Terminal
Please be careful when wiring the input line. Improper connection would cause damage to power supply.
·
Each terminal wiring must be held under the condition without no input.
·
When applying Protection Ground, use the terminal with the symbol ‘ ’ or use fixing screw to the (sheet-metal) chassis.
·
When wiring, please separate between input & output line to improve immunity of switching noise.
·
When using Remote Sensing or Remote ON/OFF function, please prepare twisted pair or shield wire for sensing or ON/OFF
signal line, and ensure to separate from the output (load) line.
·
Current rating is 25A maximum for the each terminal, but ensure to operate within rated specification of each output.

How to use Remote Sensing
CS to +V, and –S to -V terminal
1) Remove the short piece (originally attached).
by using the short piece (sheet metal)
.
2) CS & +V terminal by wiring.
(Short piece is attached when shipping.)
3) Connect -S & -V terminal by wiring.
* Note) Output shuts down when sensing line is open
* The short-piece is also connected between CNT and TOG terminals originally when shipping.
[ Pre-Caution ] Insulation Classification and Safety Conformability
Although withstand voltage is 2kVAC (1minute) between Input and Output / between Input and Chassis (Protective Earth)
for this product, insulation classification is different for each point as shown below..
Between Input and Output - - - - - - - - - - - - - - - - - - - - - - Reinforced Isolation
Between Input and Chassis (Protective Earth) - - - - - - - - - - - - Basic Isolation
Please connect AC/DC PSU (or transformer and rectifier) which has Reinforced or Double Isolation to the input terminal
of this product when using original AC input which is greater than 115V.
Furthermore, please refer Isolation and Withstand Voltage test method in the section 6-12 and 6-13 later.
